QW-V2D A vector 2D electromagnetic software applicable to the analysis of axisymmetrical devices (antennas-as big as 150 wavelength or more!, resonators, circular waveguide discontinuities). Includes QW-Editor and QW-Simulator, working in a vector 2D regime

7
QW-Editor A graphical editor for definition of geometry, media, I/O parameters and postprocessing. It comprises a library of parameterised objects and a capability for generating further objects and libraries. Conversion to and from CAD formats is also facilitated.

Examples of Application (ex.6) A tutorial example of TDR from QW-3D manual A strip-line structure terminated with a narrow grounded strip; lower half due to magnetic symmetry condition considered Time-domain electric (above) and magnetic (below) fields revealing location and kind of the discontinuity

Examples of Application (ex.7) Thawing a beefburger in a household oven; QW-3D with QW-BHM Left: system view Right: dissipated power patterns through beef and bread, produced by QW- 3D under the assumption of constant media parameters at either -20 deg or +20 deg. Left: temperature-dependent media characteristics automatically considered by QW-BHM option Right: resulting temperature pattern produced by QW-3D with QW-BHM. Due to thermal runaway effect, after 35 sec. of heating a hot spot is created in bread while beef remains frozen.
